PHOTOGRAPHBC CAMERA.

SPECIFICATION forming part of Letters latent No. 582,855, dated May 18,1897.

Application filed January 13, 1897. Serial No. 619,054. (No model.)

To aZZ whom it may concern.-

Be it known that I, ERNEsT R. FREEMAN, a citizen of the United States ofAmerica, residing at Boston, in the county of Suffolk, State ofMassachusetts, have invented certain new and useful Improvements inPhotographic Cameras; and I do hereby declare the following to be afull, clear, and exact description of the invention, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

The object of my invention is to make a simple and economicalplate-holder holding four dry plates or films to work in connection witha slide or collapsible cover containing the lens and shutter, thesebeing the objects most sought after in the articles of this description.

To these and other ends the invention consists of certain novelties ofconstruction and combinations, all as will be hereinafter described, andthe novel features pointed out in the claims of this specification.

111 the drawings, Figure 1 is a perspective view showing the cameraready for transportation. Fig. 2 represents a perspective view of thecamera-box, the front wall, which carries the lens and shutter and thelight-excluding boX or slide, being removed and the side of thecamera-box being broken out to showthe rotatable plate-holder. Fig. 3represents a perspective view of the light-excluding box or slide. Fig.4 represents a perspective view of the plate-holder. Figs. 5 and 6represent different perspective views of the plug for rotating theplate-holder. Fig. 7 represents an elevation of the shutter and itssupportingplate.

Similar reference-characters indicate the same or similar parts in allthe views.

lVithin the camera-box A is rotatabl y mounted the plate-holder B, whichis preferably a cube formed of any suitable light framework or materialand having four equal sides, each of which is provided with plateholdingstrips 0 at the top and bottom.

An angular plug D is provided with a circular portion which fits anopening N in the Wall of the camera-box and with a wing or rib by meansof which the said plug may be rotated. Said angular plug fits asimilarlyshaped socket F in the top of the plate-holder, and an arbor Eat the center of the bottom of the plate-holder fits a suitable bearingin the camera-box opposite the opening l G represents a movablepartition having an opening to expose a plate, said partition formingthe rear portion of a slide, which in this instance is represented as abox II, having its front wall provided with flanges K, which overlap thefront edges M of the camera-box. This slide or box as a whole is of suchlength that when pushed inward until the flanges K are in contact withand overlap the edges M and exclude light from leaking past the outsideof the slide the partition G is at that time in contact with the plateor the strips 0. The said sliding partition G therefore insures theplate being held at the proper angle to receive the exposure, and at thesame time it prevents light from affecting the plates which are on otherwalls of the plate-holder. By drawing the box or slide H slightlyoutward the plateholder is free to be rotated by the plug D, and onreturning the said box or slide the proper plane of the next plate isinsured. I thus avoid the necessity of any detent or stop devices fordetermining the position or plane of each plate in turn.

The plate 0, which may be the front wall of the boX or slide H or aplate attached to such front wall, is provided with a lens orlens-opening, as indicated at U, and with the shutter P, said shutterbeing pivoted at TV and provided with an elongated curved exposureopening or slot R and with an operating-handle or finger-piece S.Suit-able pins or stops V are provided to limit the movement of theshutter, and a friction clamp or catch T is connected to the plate 0 andoverlaps the shutter and bears on the lower surface thereof withsuflicient pressure to hold said shutter in any position in which it maybe placed, the lower curved edge of the shutter being smooth or freefrom notches to interfere with the clamp T.

It will be readily understood that my camera, as illustrated anddescribed, is exceedingly simple and may be constructed at a triflingcost.

Having thus described my invention, what I claim is 1. A cameracomprising in its construction ICO a rotary holder having means forsupporting individual sensitive plates or films, and a boxshaped slideor partition adapted to be moved to and from said holder to retain it inposition or release it therefrom.

2. A camera comprising in its construction a rotary holder having meansfor supporting individual sensitive plates or films, and a boxshapedslide or partition adapted to be moved to and from said holder to retainit in position or release it therefrom, said box-shaped slide having afront portion carrying a lens and shutter.

3. A camera comprising in its construction the boX A having an open endand containing a rotary plate-holder, and the box II fitted to slideWithin the open end of box A and having the rear Wall G provided with anopening and adapted to bear against one of the sides of the holder, saidbox II having also front flanges K to overlap the edges M of thecamera-box.

l. The combination with the camera-box A, of the plate-holder B having aplurality of plate-holding sides and having the arbor E and angularsocket F, and the plug D hav ing an angular portion fitting said socketF and having a circular portion fitting a eircnlar opening in thecamera-box.

In testimony that I claim the invention set forth Within I have hereuntoset my hand, this 12th day of January, 1897, in presence of twosubscribing Witnesses,

ERNES" R. FREEMAN.
